Patent number: 10561443Abstract: A method for performing image-guided embryo transfer for in vitro fertilization includes performing a pre-operative magnetic resonance imaging (MRI) scan of a subjects pelvic region to yield a first MRI image dataset. A computer applies a segmentation routine to the first MRI image dataset to yield segment data which is then used by the computer to create an anatomical model of the subjects pelvic region. The computer determines an optimal implant location based on the anatomical model and creates a three-dimensional rendering of the optimal implant location based on the first MRI image dataset.Type: GrantFiled: June 5, 2015Date of Patent: February 18, 2020Assignees: Siemens Healthcare GmbH, The Johns Hopkins UniversityInventors: Wesley David Gilson, Jan Fritz

Patent number: 10548505Abstract: A magnetic resonance method and system are provided for magnetic resonance (MR) image-guided insertion of an object into a biological tissue along a predetermined trajectory. The trajectory provides a path between a starting point and a target site within the tissue. Sufficiently high resolution images can be generated in real time to precisely guide the needle placement. A compressed sensing approach is used to generate the images based on minimization of a cost function, where the cost function is based on the predetermined needle path, artifact effects associated with the needle, the negligible changes in the images away from the trajectory, and the limited differences between successive images. The improved combination of spatial and temporal resolution facilitates an insertion procedure that can be continuously adjusted to accurately follow a predetermined trajectory in the tissue, without interruptions to obtain verification images.Type: GrantFiled: March 15, 2016Date of Patent: February 4, 2020Assignees: Siemens Healthcare GmbH, The Johns Hopkins UniversityInventors: Eva Rothgang, Arne Hengerer, Lars Lauer, Jan Fritz, Paul Bottomley, Wesley David Gilson, Robert Grimm

Patent number: 10459045Abstract: Sterile RF coil arrangements for use in magnetic resonance imaging are provided. The sterile coil arrangements can be formed by spraying or coating a curable liquid onto an RF coil housing and allowing the liquid to cure or dry to form a continuous sterile layer on the coil housing. The thickness of the sterile layer can be between 100 and 1000 micrometers. The curable liquid can include an antimicrobial or antibacterial agent, such as silver ions or triclosan, to better maintain sterility of the coil arrangement. The curable liquid can be selected such that it adheres to the housing when cured and is also removable without leaving residue behind.Type: GrantFiled: March 28, 2016Date of Patent: October 29, 2019Assignees: Siemens Healthcare GmbH, The Johns Hopkins UniversityInventors: Arne Hengerer, Eva Rothgang, Lars Lauer, Jonathan Lewin, Jan Fritz, Clifford Weiss, Katarzyna J.

Patent number: 10209325Abstract: A configurable coil arrangement for use with MRI-guided procedures is provided that facilitates optimal imaging for both pre-procedure planning and imaging of the target sites during the procedure. The coil arrangement includes a plurality of connected coil elements. Spacers connecting the coil elements can be adjustable and/or deformable to provide one or more openings in the coil arrangement of optimal size for accessing the subject within the imaged region. Individual coil elements can also be removed to provide access openings during such procedures, or left in the array for improved pre- and post-procedure image quality. The MRI system can be configured to detect configurations of the coil arrangement and modify imaging parameters to optimize image quality.Type: GrantFiled: February 29, 2016Date of Patent: February 19, 2019Assignees: Siemens Healthcare GmbH, The Johns Hopkins UniversityInventors: Eva Rothgang, Volker Matschl, Arne Hengerer, Lars Lauer, Wesley David Gilson, Jonathan Lewin, Jan Fritz, Clifford Weiss, Katarzyna Macura, Paul Bottomley

Patent number: 10180469Abstract: A magnetic resonance imaging system and method are provided that include user control of certain functions using physical gestures, such as hand motions or the like. The gesture control aspects can include one or more cameras, and a processor configured to detect and recognize gestures corresponding to predetermined commands and to provide signals to execute the commands. A verification switch, such as a foot switch, can be included to improve safety and reliability of the gesture control aspects. This switch can be used to activate the gesture detection aspects and/or to confirm a recognized gesture command prior to its execution.Type: GrantFiled: October 28, 2015Date of Patent: January 15, 2019Assignees: Siemens Healthcare GmbH, The John Hopkins UniversityInventors: Arne Hengerer, Eva Rothgang, Lars Lauer, Jonathan Lewin, Wesley David Gilson, Jan Fritz, Clifford R.

Publication number: 20150331073Abstract: A medical instrument for carrying out a percutaneous intervention in a patient is provided with a marker that is visible in an MR image. A real-time magnetic resonance image of the patient is created, so that the actual position of the marker can be identified in the real-time image. For assisting a person in the positioning of the medical instrument in an initial position suitable for the intervention, a desired position of the marker that correlates with the initial position is displayed in the real-time image. The positioning thus can be carried out relatively effortlessly and quickly.Type: ApplicationFiled: May 15, 2015Publication date: November 19, 2015Applicant: Siemens AktiengesellschaftInventors: Wesley David Gilson, Eva Rothgang
